vulcanized fiber tube

Vulcanized fiber (fish paper) tube is produced from a cotton rag base paper. This is a dense material of partially regenerated cellulose in which the fibre structure is retained

Application:Used widely for electrical fuses, where the quenching and insulating properties of the vulcanized fiber core and high strength. Commonly used in “cut-out” fuses,arc extinguishing,Fuses,circuit breaker etc. Vulcanized fiber (fish paper) tube also name Vulcanized fiber bushing ,Motor shaft spacer

Size:ID*OD Wall Thickness Color:Grey,Red Can produce various Size or Color according per customer’s requirements.
